END-LASTING MECHANISM.

Specification of Letters Patent.

Original application filed June 29, 1912, Serial No. 706,655. Divided and this application filed July 9, 1915. Serial No. 38,913.

To all whom it may concern:

Be it known that I, MATTHIAS BROOK, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in End-Lasting Mechanism, of

i which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to end lasting mechanisms and has for its object to provide improved means for conforming upper materials to the side faces of a last.

This application is a division of application Ser. No. 706,655, filed June 29, 1912, Lasting machines.

A feature of the invention consists in an end embracing band and a support for the closed end of the band which is adjustable to position the band transversely. In the illustrated embodiment of the invention a heel embracing band is provided with a support which is also adjustable to position the band longitudinally of a lasting head and relatively to heel lasting wipers.

A further feature of the invention consists in novel adjusting means constructed and arranged for convenient operation in positioning an end embracing band and maintaining it in adjusted position.

Other features of the invention consist in novel characteristics of construction of a heel embracing band.

These and other features of the invention, including certain more important details of construction and combinations of parts, will be understood from the following description of the illustrated embodiment of the invention and will then be pointed out in the claims.

Figure 1 of the drawings is a perspective view of a heel embracing band mechanism embodying this invention. Fig. 2 is a perspective view of a heel band embodying a feature of this invention. Fig. 3 shows the improved heel band mechanism incorporated in a heel lasting mechanism. Fig. 4 illustrates a. use which will be explained.

The heel lasting carriage 2 is mounted on a support 4 and contains a heel post slide 5 operated by rack teeth and a pinion 6 through a hand wheel, not shown, to draw the heel post and the shoe thereon backwardly into the heel lasting means. These means are supported in a head 10, which is connected to the carriage at 11, and comprise heel embracing wipers 12 are: devices for operating the wipers, and a heel embracing band mechanism.

The band mechanism includes a band 15, illustrated as embodying the invention defined in prior Patent No. 1,108,101, granted on my application August 18, 1914. This band is molded to fit the sides of .the shoe in accordance with a feature 01' the'present invention, and is formed ,to present normally the lower-edges of its opposite end portions appropriately nearer together than the upper edges so that when it is closed by its operating means 16, 17, 18, 10, 20, Figs. 3 and 4, its lower edges engage the shoe first and the area of engagement spreads toward the upper edges of the band and the shoe bottom. This results in working slack stock upwardly to the edge of the shoe and into the field of operation of the wipers. The

lower portions of the band ends are made independently elastic, by recessing them at 14, to enable them to adapt themselves to the width of the last while the upper edges are brought into firm engagement with the shoe during the band closing operation.

- The band is also, in accordance with a feature of this invention, formed to present an opening that is a little narrower than the width of the heel portion of the shoe and its inner face is formed of materials that produce friction against the shoe upper stock so that as the shoe on the heel post is drawn backwardly into the band by the rotation of pinion 6, the narrow band is caused to engage the upper frictionally at the corners of the heel of the shoe and forwardly tension the upper tightly around the rear end of the last.

The front end portions of the band 15 are supported in proper vertical relation to the plane of action of the wipers 12 by the operating means 16 which for this purpose act through the band chain 22 and clips 23 depending from the chain. The chain is formed with a block 24 at the closed rear end of the band and through this block the rear portion of the band is sustained in proper vertical relation to the wipers 12 by the head 26 of rod 25 which extends to the rear end of the lasting head. The rod is threaded into head 26 and, being restrained from endwise movement in the lasting head 10, can be turned to adjust theband longitudinally in the lasting head relatively to the wipers.

The block 24 which supports the rear end of the band is mounted to slide on the head 26 of rod 25 and is connected through slide 27 and lever 28 with an adjuster 30. The adjuster is a rotatable rod restrained from endwise movement and threaded into a block 32 which is pivotally connected with the lever 28. The lever is fulcrumed at 33 so that rotation of the threaded rod 30 will set and hold the band in adjusted position transversely of the lasting head.

Having explained the nature of this invention and described a construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States 1. In a lasting machine, the combination with an end lasting head having end last ing wipers, and an end embracing band carried in the lasting head, of an adjuster connected with the closed end of the band and adapted for manipulation to set the band transversely of the head relatively to the wipers.

2. In a machine of the class described, the combination with a lasting head, and an end embracing band carried in the head, of a supporting slide connected with the closed end of the band and mounted for movement transversely of the head, a lever connected with the slide, and an adjusting device connected with the lever and adapted to set and hold the band in adjusted position.

In a lasting machine, the combination with an end lasting head having end lasting wipers, and an end embracing band carried in the lasting head, of means for adjusting the band longitudinally and transversely in the lasting head relatively to the wipers.

4. In a lasting machine, the combination with an end lasting head having end lasting wipers, and an end embracing band carried in the head, of an adjustin rod connected with the band and extending to the outer end of the lasting head and adapted for operation to set the band forwardly and backwardly in the lasting head with relation to the wipers.

msaerr wipers, of an end embracing band carried in the lasting head, and supporting means for the closed end of the band which is movable -to adjust the band transversely of the lasting head relatively to the wipers.

7. In a. lasting machine, the combination with a lasting head having end lasting wipers, of an end embracing band carried in the lasting head, a supporting slide for the band mounted for adjustment transversely of the lasting head and relatively to the wipers, and a support for the slide which is mounted for adjustment longitudinally of the lasting head relatively to the wipers.

8. In alasting machine, the combination with a lasting head having end lasting wipers, of an end embracing band carried in the lasting head, and a support for the closed end of the band which is adjustable to position said end of the band transversely and longitudinally ofthe lasting head relatively to the wipers.

9. In a lasting machine. the combination with an end lasting head having end lasting wipers, -of an end embracing band adjustable transversely of the machine rela tively to the wipers and means for holding the band in adjusted relation to the wipers.

10. In a lasting machine, the combination with an end lasting head having end lasting wipers, of an end embracing band, and means for adjusting the closed end of the band transversely of the machine relatively to the wipers.

ll. In a lasting machine, the combination with an end lasting head having end lasting wipers, of an end embracing band, means for supporting the ends of the band, and means connected with the middle portion of the band for adjusting that portion of the band transversely of the machine relatively to the ends of the band and holding it in adjusted position.

12. In a lasting machine, the combination with an end lasting head having end lasting wipers and an end embracing band. of means for adjusting the band transversely of the machine relatively to the wipers and holding it in adjusted relation to the wipers.

13. In a lasting machine, the combination with a heel lasting head, of a heel embracing band and means for operating the band, said band being formed with an opening narrower than the width of the heel portion of the shoe and having an inner face of material that produces friction against shoe uppers, and means for drawing the shoe into said band to cause the narrow band to engage the shoe frictionally at the corners of the heel and forwardly tension the upper tightly around the rear end of 1) the last, substantially as described.

In testimony whereof I have signed my name to this specification.
